After standing up to a group of obnoxious older boys on a train, 12-year-old Ryoma Echizen ends up playing  tennis against a high school star. Ryoma seems confident, but does he stand a chance against his opponent's physical advantages?
Come on, Grandma!
You invited me and now you're late!
Mensch! Omi kommt zu spät,
obwohl sie mich doch eingeladen hat!
Cielos, abuela…
Tú me invitas y luego llegas tarde.
Venga, abuela…
Primero me invitas y luego llegas tarde.
Mamie exagère,
elle m’invite et c’est elle qui est en retard.
Qual é, vó!
Você que me convidou, e agora se atrasa.
